The backs of 1987 Topps baseball cards contained a fun feature: amazing facts about the players! Or in many cases, declarative statements regarding their hobbies ("Candy Maldonado finds traveling an enjoyable experience.") You learned where players went to high school, what other sports they like, and the names of their children. But some cards shared more.

That year, the Topps designers chose to frame player photos with a distinctive wood-grain trim. It didn't resemble anything that sprouted in the natural world—it was more like the faux wood siding on your mother's Plymouth station wagon, or the flimsy wood-effect paneling on the walls of your neighbor's basement...[But] if you suffered from severe cartophilia, as I did, then you simply had to have it."
